Abstract

Spatial transfer function for wide band wireless communication system is analyzed by using FDTD and DFT method. Ray-based method is not sufficiently accurate, when the size of objects on the propagating path is comparable to the wavelength. In our proposed method, the tranfser function can be obtained exactly by using the FDTD method. For the numerical examples, the transfer functions in an aperture of the waveguide are calculated by proposed procedure. Furthermore, experimental verification is made by using two-dimensional propagation system, which is constructed of copper plates, antennas and vector network analyzer. The proposed algorithm is valid for estimating of the spatial transfer function.
